Subject Incredibly slow response to Scan
Date Fri, 08 Oct 2010 01:33:39 GMT

 

 J-D et.al
I've put the mapreduce issue that I had in the back burner for now.
I'm getting incredible slow response to Scan..

On a 10 node cluster for a table with 1200 regions ..it takes 20 minutes
to scan a column with given value..Got 100 or so records for the response..

Is this normal?

thanks
venkatesh
PS. setCaching(100) ..did n't make a dent in performance
